Subject: Fix up/down key navigation
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=be64cbcdc22952ce2fa9f902e153e3bd9f4a08c9;p=profile%2Fivi%2Fclutter.git

Fix up/down key navigation

The behaviour of ClutterText around the initial position is still
a little bit erratic.

This commit fixes the key navigation with Up and Down arrows around
the first line of text.
